6 Monitoring deduplication, compression, and performance After backup jobs have run, the DR Series system tracks capacity, storage savings, and throughput on the DR Series system dashboard. This information is valuable in understanding the benefits of the DR Series system. Note: Deduplication ratios increase over time. It is not uncommon to see a 2-4x reduction (25-50% total savings) on the initial backup. As additional full backup jobs are completed, the ratios will increase. Backup jobs with a 12-week retention will average a 15x ratio, in most cases. 77 Setting up the Dell™ DR Series System on Symantec™ NetBackup™ | July 2015

Monitoring deduplication, compression, and performance

After backup jobs have run, the DR Series system tracks capacity, storage savings, and throughput on the DR

Series system dashboard. This information is valuable in understanding the benefits of the DR Series system.

Note

: Deduplication ratios increase over time. It is not uncommon to see a 2-4x reduction (25-50% total

savings) on the initial backup. As additional full backup jobs are completed, the ratios will increase. Backup jobs

with a 12-week retention will average a 15x ratio, in most cases.
